I can’t enjoy things

When I make plans to have a holiday or to do something for enjoyment I cannot actually take the time to live in the moment and enjoy it. Even the fun things in life just become a to do list for me to cross off until I can relax. It’s exhausting because other people take their time and enjoy things (as they should) and they become a barrier to me completing a task so I stress out internally screaming at people to get out of my way. This sucks.
